Expand bright pixels and shrink darker pixels.


Method #

This node iteratively expands the bright pixels in an image, filling in darker areas and brightening the overall image. Useful for expanding a mask which has been generated too tight around the subject.


These properties control the core behaviours of the node.

Blend AmountChanges the opacity of the new effect over the original image.
Iterations (Effect Size)How many times the dilate function is run.
ModeWhich directions the image is dilated in.
  • Horizontal + Vertical : Both horizontal and vertical are dilated.
  • Horizontal : Only horizontal is dilated.
  • Vertical : Only vertical is dilated.
  • Cross : Both diagonals are dilated.
